You need to find out two things then in imp/lib/IMAP/Client.php. Why  
_usetls is set to true, what the wrong argument mentioned in the error  
message is, probably _host.

I just edited the default Client.php and you were correct that _usetls was
set to true. I'm not sure why it was set that way by default.  Even after I
manually set it to false in both places it's still not working properly.

   var $_usetls = false;

    /**
     * Constructor.
     *
     * @param string $host      The address/hostname of the IMAP server.
     * @param string $port      The port to connect to on the IMAP server.
     * @param string $protocol  The protocol string (See, e.g.,
servers.php).
     */
    function IMP_IMAPClient($host, $port, $protocol)
    {
        $this->_host = $host;
        $this->_port = $port;

        /* Split apart protocol string to discover if we need to use either
         * SSL or TLS. */
        $tmp = explode('/', strtolower($protocol));
        if (in_array('tls', $tmp)) {
            $this->_usetls = false;
        } elseif (in_array('ssl', $tmp)) {
            $this->_usessl = true;
        }
    }



Any other ideas what would be causing this?
